  • Patent number: 7732124
    Abstract: A color-image forming method in a silver halide color photographic light-sensitive material, having the steps of: performing exposure of the light-sensitive material cut into sheets; and subjecting the exposed light-sensitive material sheets to photographic processing, while conveying them with conveying rollers, with the sheet conveying speed being 40.0 to 100 mm/sec; wherein the light-sensitive material to be exposed contains any of: 1) a dye-forming coupler of formula (IA), 2) a compound of formula (I), and 3) 1.4 mg/m2 or more of a compound of formula (II); wherein R? and R? are a substituent; Z is a hydrogen atom, or a coupling split-off group; A is an alkyl group, M is a cation, and R is an atom or group having 100 or lower total molecular weight.

  • Patent number: 6817789
    Abstract: A photosensitive material processing apparatus includes a printer section for recording an image on photographic paper by exposure. There is a processor section for photographic development of the photographic paper. A drier section dries the photographic paper. A type bar code reader reads and inputs type information of a type of the photographic paper. A condition table memory is used to generate information of a transporting speed of the photographic paper and other processing conditions according to the type information being input, so as to control at least one of the printer section, the processor section and the drier section.

  • Patent number: 5884115
    Abstract: A first roller, which contacts a photographic printing paper with the first roller being formed longer than the width of the photographic printing paper, is disposed at the conveying direction downstream side of the photographic printing paper with respect to a developing tank. A second roller, which contacts the photographic printing paper with the second roller being formed shorter than or equal to the width of the photographic printing paper, is disposed at a position at which the photographic printing paper can be nipped by the first and second rollers. The first and second rollers form squeeze rollers. Because the clearance between the sides of the squeeze rollers in the widthwise direction of the photographic printing paper is wide, the squeezed processing solution conveyed from the clearance to the downstream side of the photographic printing paper is small.
